Fix InvalidArgumentException on commit hook

Browse source 
Summary:
Fix a regression introduced here:

96ae4ba13a

I reproduced this exception executing "svn commit" on a hosted repository.

That crash happened because the PHP getenv() function can return false.
But, that is a very terrible value that blasts the non-string-empty check.

So, now the default getenv() value is skipped, without causing problems.

Closes T15253
Ref T15190

Test Plan: - I've run `svn commit` and I have not encountered any issue now
