Close file in log_client.py

[robert-ros]

In rcomponent/src/rcomponent/log_client.py the file must be closed, otherwise it leads to a high virtual ram usage. Then the CPU slows down.

rcomponent/src/rcomponent/log_client.py

Line 279 in a79984d

file.write(log_msg)

This issue affects the command manager
