wallet: return accurate error messages from Coin Selection

and not the general "Insufficient funds" when the wallet
actually have funds.

Two new error messages:

1) If the selection result exceeds the maximum transaction weight,
   we now will return: "The inputs size exceeds the maximum weight".

2) If the user preselected inputs and disallowed the automatic coin
   selection process (no other inputs are allowed), we now will
   return: "The preselected coins total amount does not cover the
   transaction target".
