Support passing partial deviceIdentifier for `--device` flag

[rosen-vladimirov]

Is your feature request related to a problem? Please describe.
When using --device flag to tns run (or debug) command, I would like to be able to pass only part of the device identifier. I know I can copy the whole device identifier from the output of tns device command, but when working in a narrow terminal, the device identifier in the output of the command is often split on two rows and it is hard to copy the full id.

Describe the solution you'd like
In case I have device with identifier ff8de22d8b25f3aa3d822d5e016e65eb9747d1f2, I would like to be able to pass --device ff8

Describe alternatives you've considered
