Ocassional false positive of Declared as collator for unneeded

[alexggh]

There seems to be a race between a collator deciding to connecting to the assigned validators and the validator processing its own view updates, where it decides what parachains it is assigned to, so it will decide to wrongly disconnect a collator that advertises itself, see

This will probably, cause collators to miss advertising on a single block, if it gets these race on all validators that is assigned to(unlikely), so probably only test network are affected by this because those run with validator group size of 1.
