cli_to_rpc_string() generating incorrect rpc string if <app> tag text contains a hyphen char

[ipmonk]

// the following generates output that results in an exception

>>> d.cli_to_rpc_string("show platform app-controller app l2ald-agent complete")
"rpc.app_controller_show(app='l2ald-agent', complete=True)"

>>> d.rpc.app_controller_show(app='l2ald-agent', complete=True)
/usr/lib64/python3.7/site-packages/jnpr/junos/device.py:858: RuntimeWarning: An unknown exception occurred - please report.
  "An unknown exception occurred - please report.", RuntimeWarning

// this is due to the hyphen inside the <app> tag. substitute for an underscore and the rpc works:

>>> d.rpc.app_controller_show(app='l2ald_agent', complete=True)
<Element app-object-info at 0x7f9c4008c3c0>

// problem originates from the | display xml rpc output.
