Changed tests for 100% coverage

Before the bitcoinAddressProvider would instantiate
Danwe\Bitcoin\Address instances which would result in
the static property holding the address parser being set
already. This would prevent from 100% coverage. Now
the provider won't instantiate addresses, instead a
address string provider is used for the tests.
