Fix some Perl array tests (#259)

* Perl allow several pairs of brackets to define arrays: (), [] and several others

Since 7ff2eda Perl expression translator uses [] instead of ().
Fix tests to reflect that

* Fix Perl tests after changes in d9ae2b9

* Fix Perl tests after ba114f2

* Fix Perl array subscript translation tests

.first and .last and subscript was implemented initially in c20661a
