selftests: mptcp: add a check for 'add_addr_accepted'

Browse Source 
The previous patch fixed an issue with the 'add_addr_accepted' counter.
This was not spot by the test suite.

Check this counter and 'add_addr_signal' in MPTCP Join 'delete re-add
signal' test. This should help spotting similar regressions later on.
These counters are crucial for ensuring the MPTCP path manager correctly
handles the subflow creation via 'ADD_ADDR'.
