Title: [Qt] sendcoinsdialog: convert QMessageBox usage to message()

- this change ensures that the GUI is shown for warnings/errors in
sendcoinsdialog, because of message() taking care of that for modal
messages
- also changed 2 warning message into error messages and removed "Error:"
in front of the actual error message string
