Unable to use library directory on Windows #280
Description
On one of my student's Windows machine we find the following:

It may need to be removed manually. Here is the directory on Windows:

When we move the working directory out of C:\Users\calvo\Documents\Arduino/libraries then we no longer get that error. Instead we get the following:
Library conforms to Arduino library specification... 1.0 No tests directory at... C:\Users\calvo\Documents\Arduino/libraries/Adafruit_BusIO/test Environment variable EXPECT_UNITTESTS is... (NilClass) Skipping unit tests... In case that's an error, displaying contents of base directory: Interestingly, we are running the same version of Arduino-cli (0.13.0), but his environment thinks that the library conforms to specification 1.0 while mine thinks that the library conforms to specification 1.5.
