There should never be the case where the target of a :call Sexp is a
symbol, it should always be either `nil` or a Sexp. Brakeman should not
be building invalid Sexps.

Surprised this never caused any errors

Brakeman was generating invalid call Sexps with `:_hamlout`
as the target for `_hamlout.options` and `hamlout.buffer`.
However, these special Sexps were not really be handled in Brakeman
anywhere, and there was no real reason to make special Sexps for them.

Conflicts:
	test/tests/test_brakeman.rb

because it was checking the options for the wrong value

Allow comparison of versions of unequal length

Basically, because the tracker caches the template names and the
rescanner was deleting the templates without clearing the cache. Should
use Tracker#reset_template instead

because there's an error when string interpolation has more than one
expression inside.
