chdir does not work as expected

[DavidHuber-NOAA]

Expected behavior
The fsutils.chdir contextmanager should navigate to the chosen directory for the duration of a with statement and then return to the previous working directory. If chdir is unable to navigate to the chosen directory, it should raise an exception. Also, tests should be in place to verify that chdir works as expected.

Current behavior
chdir does navigate to the chosen directory, but it always states

WARNING: Unable to chdir({path})

Additionally, when attempting to return to the previous working directory at the end of the with, it states it is unable to yield to it.
Lastly, there are no tests for the entirety of the fsutils module, including the chdir contextmanager.

Machines affected
All

To Reproduce

from wxflow import chdir

with chdir("/"):
    print("We are now in /")

Context
Found while attempting to engineer a solution for NOAA-EMC/global-workflow#2994, which requires navigating to HOMEgfs to run git commands.

Detailed Description
Nothing further.

Possible Implementation

    cwd = os.getcwd()
    # Try to change paths.
    try:
        os.chdir(path)
    except OSError:
        raise OSError(f"Failed to change directory to ({path})")

    # If successful, yield to the calling "with" statement.
    try:
        yield
    finally:
        # Once the with is complete, head back to the original working directory
        os.chdir(cwd)
