Add OT&E verification that a domain was successfully created in sunrise

We already have verifications that a domain application was created in sunrise
- which checks for end-date sunrise. Start-date sunrise has checks that a
domain (not application) was created. There's no need to specifically check for
a signed mark, since a successful domain create during sunrise must have a
signed mark in it.

Also removed the requirement for end-date sunrise / landrush testing.
