Fix a mismatched method definition in PhabricatorHomeProfileMenuItem

Summary: Fixes T12187. Ref T12190. See T12190 for discussion of why this escaped notice.

Test Plan:
  - Commented out the `error_reporting()` clause around file inclusion.
  - Reproduced the error in PHP7.
  - Corrected the method signature.
  - Reloaded the page, no more error.
