Subject: autoload/gitcha.vim: Remove cruft after switching to `complete()`

Remove all the cruft from 60bc8ea8b3b7be511c4240ca1d7dc1cc1149b113:

* Don't store user-defined 'completefunc' any more since we no longer
  change that setting.
* Remove the commented `a:findstart` code, which is no longer relevant
  since this function is no longer a 'completefunc'.
* Remove commented test & debugging code
* Remove the `gitcha#StartGitSHACompletion()` function, which was there
  only to facilitate mapping to the user completion function defined in
  'completefunc' using the Vim-assigned mapping `<C-x><C-u>`. Our map
  now directly invokes `gitcha#GitSHAComplete()`.
