PostReview: Remove redundant null-check

Browse Source 
The `current` variable is initialised with the return value from the
scanLabels method, which always returns a Map instance, which may be
empty, but does not return null.

It is therefore not necessary to check for `current` being null in the
initialisation of `allApprovals`.

Removing the null-check prevents FindBugs from warning about potential
null-pointer exceptions on subsequent dereferences of `current` that
are not guarded by null-checks.
