Fix escaped quotes

[williamthome]

This PR fixes escaped quotes.

Before:

1> rp(template_compiler:compile_binary(<<"{% print 'Hello \\'world\\'' %}">>, <<"tmp.tpl">>, [], [])).
{error,[82,101,97,99,104,101,100,32,101,110,100,32,111,102,
        32,
        [60,60,"\"tmp.tpl\"",62,62],
        32,105,110,115,105,100,101,32,97,32,99,111,100,101,32,98,
        108,111,99,107,46]}
2> io:format("~s~n", [[82,101,97,99,104,101,100,32,101,110,100,32,111,102,
           32,
           [60,60,"\"tmp.tpl\"",62,62],
           32,105,110,115,105,100,101,32,97,32,99,111,100,101,32,98,
           108,111,99,107,46]]).
Reached end of <<"tmp.tpl">> inside a code block.

Now:

1> template_compiler:compile_binary(<<"{% print 'Hello \\'world\\'' %}">>, <<"tmp.tpl">>, [], []).
{ok,tpl_423b67510ab04afcc797794b8a9d5e69319b8cc6}
ok
2> tpl_423b67510ab04afcc797794b8a9d5e69319b8cc6:render([],[],[]).
[<<>>,
 [<<"<pre>">>,
  <<"&lt;&lt;&quot;Hello &#39;world&#39;&quot;&gt;&gt;">>,
  <<"</pre>">>]]

The reason is that the compiler could not find the end of the quotes.

That's the result of running those new tests in the master branch:

Looks like we have a totally unrelated problem with ex_doc.

[williamthome]

@mworrell could you please rerun the actions?
I've no permission to do so.

[mworrell]

Great! This works again, after all your other fixes.
