[#889] Overload `getAlias`

Description

Problem: In !1260 (merged), we added the type SomeAddressOrAlias and overloaded resolveAddress to work with both SomeAdressOrAlias and AddressOrAlias kind.

However, getAlias still only works with AddressOrAlias.

Solution:

• Rename the ResolveAddress typeclass to simply Resolve
• Add a getAliasEither method to the Resolve typeclass
• Implement getAlias and getAliasMaybe in terms of getAliasEither
• Replace HasTezosClient.findAlias method with the more general HasTezosClient.getAliasesAndAddresses. This can be used to implement both resovleAddress and getAlias.
