globalcontributions: Tolerate trailing spaces on special:contributions

Why:
- When accessing Special:GlobalContributions, if the target to look for
  ends with a whitespace, the page returns no results, showing an error
  stating that the target is not a valid user name instead. To test it,
  you can provide a target ending with a whitespace in the URL, like
  ?title=Special:GlobalContributions&target=172.22.0.1+&namespace=all
  (note the plus sign at the end of the target).
- When accessing the page, different code paths seem to expect having
  the user name provided in different ways (reading it from the request
  itself, getting it passed as a value, or reading it from the
  controller's $opts attribute).

What:
- Cleanup the target before the actual logic for the contributions
  special pages starts, making all contributions pages (including global
  contributions) read the user name after stripping the leading and
  trailing whitespaces, if any.
