Remove adding a verbose option to the run arguments

[antalszava]

Context

In QiskitDevice, a verbose option is being added by default to the keyword arguments to be passed to the backend. This has caused warnings when submitting jobs to IBMQ.

The lines that set the verbose to false have been added a while back in #44. Likely, this used to be a valid backend option, however, at the moment there Qiskit doesn't seem to support it.

Changes

Removes the addition of the verbose option.

Closes #145

Sounds good.

Does this need a changelog entry?
