Fix: Modify retrieving path of Mechanical in tests

[dipinknair]

Use get_mechanical_path instead of find_mechanical in remote_session_launch tests

@dipinknair which issue is this associated with?

@koubaa

Came across this issue while debugging remote_session_launch test failures locally. Since find_mechanical() does not check config.txt , some test were failing because of not able to retrieve path.

@dipinknair we run on containers that put mechanical under /install/ansys_inc/vNnn. So find_mechanical should work there. Do you know why it didn't?

This is to facilitate testing locally so that we can debug further issues that we see in tests. This is not a fix for the test failures happening in github runners but fix to run the test locally since Pool test are also using find_mechanical. find_mechanical works fine in github runners.

@dipinknair in that case I suggest leaving a fallback to find the path if there's nothing in the config, otherwise this will require setting the path before the test can run.

get_mechanical_path takes care that and find arg set always true for this function which falls back to find mechanical if no path found from the config file
