Variable Explorer throws an error instead of displaying contents when attempting to inspect any loaded modules

See original GitHub issue

Description

I double-clicked a module which was the value of a dict in variable explorer and got an error.

What steps will reproduce the problem?

Import a module (example: import os)
Initialize a dict in a variable (example: d=dict())
Assign the module to the dict (example: d['os']=os)
Double-click the cyan entry of your variable on variable explorer
Double-click the white entry which corresponds to your module
You see the error reporting window.

What is the expected output? What do you see instead?

I expected seeing the global variables defined in the module, but I got an error reporting window.

Please provide any additional information below

@CAM-Gerlach, it should be enough with catching the TypeError generated by this and then pass if that happens.

Yeah, I think that was the change that I mentioned vaguely remembering above since it was potentially related to another issue I was having. In any case, this should simplify the test since it only needs to deal with the general case.
