remove_path causes an errror when module loading and unloading

[francinelapid]

Describe the bug
module load-ing two modulefiles that use remove_path will cause an error when one of them is eventually attempted to be unloaded.

To Reproduce

1. Create 2 modulefiles that use remove_path
2. module load both modulefiles
3. module unload either of the modulefiles

This will result in an error similar to:

$ module unload remove_another_path 
Lmod has detected the following error: Unable to load module because of error
when evaluating modulefile:
     .../remove_path.lua:
...Lmod-8.7.32/src/MainControl.lua:339: attempt to
call a nil value (method 'trim')
     Please check the modulefile and especially if there is a line number
specified in the above message 
While processing the following module(s):
    Module fullname  Module Filename
    ---------------  ---------------
    remove_path      ...

Desktop (please complete the following information):

• OS: Linux
• Linux distribution: SLES
• Lmod Version: 8.7.32
• For Lmod Versions 8.7.7+, please run "module --miniConfig" and
  include the output here.

At the moment, we have a patch in place that changes the remove_path dependency to MainControl.quiet in MC_DependencyCk.lua (#670). This fixes the error for us.

That was the correct fix. Thanks for the bug report. Please use the version from the testing branch to see if works for you.
