Completions are not shown in `compile' minibuffer when helm-mode is on.

Hi.
This package is fantastic for shell, but recently the new update broke "compile" if helm is used.

With "helm-mode" on.
After invoking "compile" and the mini buffer is ready (with "make -k " typically), pressing TAB gives the following messages:

Minibuf-1 /some-directory/ t nil boundaries metadata signal (error) bash-completion-comm mapcar process-get completion-ignore-case try-completion t test-completion default-directory bash-completion-nospace bash-completion-use-separate-processes] 8

(fn STR PREDICATE ACTION)] nil nil nil t nil t helm-comp-read-get-candidates helm-cr-default helm-pattern] 6]’

This doesn't happen if "helm-mode" is off or "bash-completion" hasn't been initialized.

Yes, something was really wrong with the way bash-completion handled predicate functions passed to dynamic completion functions.

I fixed that and it looks like bash completion now works again with helm mode enabled. Please let me know if doesn't work on your system.
