MDL-51524 tests: Fix broken tests
The upgraded version of HTML2Text highlighted some bugs in our unit tests.
In the IOS test, the HTML content includes a couple of patches of
In the previous version of HTML2Text, these were being converted to
breaking spaces. In one of these cases, it was then removed due to a trim.
The expected texts have been converted to use the correct non-breaking spaces.
In the case of the trimmed one, it is no longer trimmed as non-breaking
spaces are not trimmed.
This gives a truer reflection of the actual text.
In the case of the Outlook test, this trailing whitespace is not present in
the source. It was likely caused by a bug in the previous version of
HTML2Text.
In the case of the weblib change, the test was just wrong. Both of the
actual characters are encodings for an HTML bullet (decimal and hex) and
should both be converted to the relevant UTF8 representation of this
bullet.
