Sometimes co-signor can not be removed

[postoronnii]

WTR:

1. Go to https://desktop-build.symboldev.com/
2. Create multisig account with one co-signor
3. Try to remove co-signor

Result: Sometimes I am getting the error and co-signor can not be removed:
Uncaught Error: Failure_Multisig_Max_Cosignatories at MapSubscriber.eval (TransactionService.js?6d07:102) at MapSubscriber._next (map.js?ebb6:35) at MapSubscriber.Subscriber.next (Subscriber.js?1453:53) at ThrowIfEmptySubscriber._next (throwIfEmpty.js?b4d5:32) at ThrowIfEmptySubscriber.Subscriber.next (Subscriber.js?1453:53) at TakeSubscriber._next (take.js?b7d7:40) at TakeSubscriber.Subscriber.next (Subscriber.js?1453:53) at MergeMapSubscriber.notifyNext (mergeMap.js?a6c5:85) at SimpleInnerSubscriber._next (innerSubscribe.js?cf86:14) at SimpleInnerSubscriber.Subscriber.next (Subscriber.js?1453:53) hashAndAggregateBonded listener is closed due to error!

@bassemmagdy @cryptoBeliever the issue is fixed in this PR #1595

[cryptoBeliever]

@NikolaiB but PR is not accepted yet. Issue should be tested after PR acceptance and next in dev branch after branch. Moving back to code review column.

@NikolaiB could you retest in dev and close if it's fine?

Tested, the issue is fixed.
