fix(index-async): properly inline text containing $$

When using `'...'.replace(regex, replacement)`, any instances of `$$` inside `replacement` will be
converted to `$` (see
[mdn](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace#Specifying_a_string_as_a_parameter).
Thus, for example `$$minErr` and `$$moduleName` are converted to `$minErr` and `$moduleName`.
This commit fixes it, by first using `'...'.split(regex).join(replacement)` instead.

Fixes #283
Closes #286
