MDL-72871 cleanup: Remove incorrect whitespace from codebase

Differences can be checked with git diff --ignore-all-space and
that will show that the only non-whitespace change is in a test
in the git lib/tests/html2text_test.php file. In that case the
whitespace has been replaced by a quoted string (of whitespaces)
keeping the test 100% equivalent and workarrounding the whitespace.
