pps: remove input_file_id from get_logs signature
pps: remove input_file_id from get_logs signature

in at least pach 1.7.3, there is no `input_file_id` field in the `GetLogsRequest`, so asking for logs raises an exception.

this fixes the issue on pach 1.7.3, but obviously removes support for some older versions (such as 1.6.5). i dont know what your strategy for dealing with versions is.
