run_tleap raises exception running on Ambertools 19

[badisa]

It appears that the version of tleap that comes with ambertools 19 (from conda) has added the following message when it exits Exiting LEaP: Errors = 0; Warnings = 0; Notes = 0. which triggers the failure condition in check_command which looks for "Error" in every line as a failure case.

Moving to Ambertools 18.13 fixed this. Took a while to determine why as it seems that the log_debug_output flag doesn't provide any additional information in the scenario. Even if I set all loggers to debug.

The traceback:
