<runtime_steps.rb> Bug 949251 - Add file check to V1 snapshot/restore test

Cuke test for snapshot/restore on V1 carts didn't check if changes
post-snapshot were persisting, and so failed to catch the condition described
in https://bugzilla.redhat.com/show_bug.cgi?id=949251

Added lines to snapshot/restore test to fix
<controller/test/cucumber> Bug 949251 - fix jboss* snapshot/restore tests

The snapshot/restore tests for the jboss* carts were using very
granular stepdefs instead of the more concise (and thorough) combined
stepdef from runtime_steps.rb. I updated these tests to take advantage
of the updated combined stepdef.
<oo-restore> Bug 949251 - forgot to add actual oo-restore fix

Call to restore.sh wasn't passing through args, added "$@" to
restore.sh in oo-restore call to guarantee "INCLUDE_GIT" arg gets
included
