Feature/use expect event in test logs assertions #1232 (#1343)

Browse Source 
* Add BigNumber support to expectEvent/inLogs (#1026)

* switched direct logs array check to expectEvent method in AllowanceCrowdsale.test.js

* Refactor expectEvent.inLogs function to use simple value number check

* Introduced should.be.bignumber method to compare BigNumber values

* Use expectEvent to test logs (#1232)

* Removed trailing space

(cherry picked from commit 536262f2ec)
