[tests] check send MLR.req for MAs when PBBR is enabled (#5337)

Browse Source 
This commit adds one test to verify that if a node subscribed MAs when
there is no PBBR in the network, it should still be able to send
MLR.req after PBBR is enabled.

This is a case that wasn't tested in existing tests.
