Don't run legacy transition tests when shell transitions enabled

Specifically, any tests relying on legacy transition types are
not relevant to shell transitions.

The replacement(s) are going to be similar tests which instead
check the reported TransitionInfo. We can no-longer CTS test
the actual animations since those depend on shell implementation.
