When loading a ETH address as vesting contract we show a cryptic error
message, which non tech-savy end users don't understand, this commit
changes it to something more human readable.
We allow users to enter and load a contract that probably isn't a
vesting contract.
The `getInfo` function in the `vesting` folder is very prone to possible
errors, and benefits from some parallelization between all the method
calls.
We allow hereby to enter a contract address in search and once on the
contract profile page we provide a link to the detailed vesting
information if available.
