Update contract call function to use w3.eth.default_block instead of 'latest' (#2846)

* Update contract.py

The default parameter "latest" ignores when w3.eth.default_block is set.

* Leafyoung/master (#1)

* add newsfragment

* Change block_identifier to None instead of 'latest'

* Classify newsfragment as 'bugfix' instead of 'internal'
