[Tex/LaTex] Removing full stop after first name initial in biblatex, for all authors

biblatexpunctuation

I am using biblatex to format my references and I want to format them according to

<LastName> <FirstNameInitial>, <LastName> <FirstNameInitial>

and so on. In order to remove the standard dot/fullstop after the initial I have tried to use
Modify the last-name first-name separator in biblatex's authortitle

The problem here is that it only formats the first author after the desired standard. A minimum working example (copied from the above question) is given below. I am almost sure that it is some small part of the answer given in the linked question that needs to be changed, but my biblatex coding skills are at a minium. A picture of the output code is shown in the above linked question but I can not post it here.

\RequirePackage{filecontents}
\begin{filecontents}{sample.bib}
@ARTICLE{liu:11,
  author = {Peter Fox and Richard Rabbit and Franc Bird},
  title = {Animals are the better humans},
  journal = {Horse and Hound},
  year = {2011},
  volume = {10},
  pages = {11--15}
}
\end{filecontents}

As pointed out by Audrey in a comment, one should amend the solution linked in the OP's comment with setting terseinits=true and tinkering with \DeclareNameAlias for the name sorting order.

\documentclass{article}

\usepackage[style=authortitle,firstinits=true,terseinits=true]{biblatex}

\makeatletter
\renewbibmacro*{name:last-first}[4]{%
  \ifuseprefix
    {\usebibmacro{name:delim}{#3#1}%
     \usebibmacro{name:hook}{#3#1}%
     \ifblank{#3}{}{%
       \ifcapital
         {\mkbibnameprefix{\MakeCapital{#3}}\isdot}
     {\mkbibnameprefix{#3}\isdot}%
       \ifpunctmark{'}{}{\bibnamedelimc}}%
     \mkbibnamelast{#1}\isdot
     \ifblank{#4}{}{\bibnamedelimd\mkbibnameaffix{#4}\isdot}%
%      \ifblank{#2}{}{\addcomma\bibnamedelimd\mkbibnamefirst{#2}\isdot}}% DELETED
     \ifblank{#2}{}{\bibnamedelimd\mkbibnamefirst{#2}\isdot}}% NEW
    {\usebibmacro{name:delim}{#1}%
     \usebibmacro{name:hook}{#1}%
     \mkbibnamelast{#1}\isdot
     \ifblank{#4}{}{\bibnamedelimd\mkbibnameaffix{#4}\isdot}%
%      \ifblank{#2#3}{}{\addcomma}% DELETED
     \ifblank{#2}{}{\bibnamedelimd\mkbibnamefirst{#2}\isdot}%
     \ifblank{#3}{}{\bibnamedelimd\mkbibnameprefix{#3}\isdot}}}
\makeatother

\DeclareNameAlias{sortname}{last-first}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@ARTICLE{liu:11,
  author = {Peter Fox and Richard Rabbit and Franc Bird},
  title = {Animals are the better humans},
  journal = {Horse and Hound},
  year = {2011},
  volume = {10},
  pages = {11--15}
}
\end{filecontents}

\addbibresource{\jobname.bib}
