Add a missing mock in DHCPAgentWeightSchedulerTestCase

start_periodic_dhcp_agent_status_check needs to be mocked
when instantiating ml2 plugin.

The test case in question was introduced by
change I5ec8adf0c4336f885d603662223caa7694708876.

Closes-Bug: #1433944
Change-Id: I2d0b57e37d10b6dbd1a06dc7bba004890e238ce6
