Add the hability to parse Glob and Folder path in modelPaths

[victorivens05]

Changed the usage of FS to GLOB. If the Path isn't a glob, it's a folder
path and to work with glob, must be turned into a glob (by adding /* in
the end).
I think the check if it hasMagic should be an outside function,
chained in a map before arg.reduce.

@victorivens05 You could setup testing as follows:

• Create a sub directory in /test/models/ - for example /test/models/globs
• Create additional sub directories and choose appropriate names matching your test cases - for example /test/models/globs/match-dir-only or /test/models/globs/match-sub-dir-files
• Put your specs into /test/specs/models/sequelize.spec.ts -> Check if the models are loaded properly :)

@RobinBuschmann I created some tests, I'm not sure if they're enough. Now how do I add them to the PR? Or I have to create another?

[RobinBuschmann]

@victorivens05 Pushing you're changes to the remote branch of the PR should be enough :) Since you've created a PR from victorivens05:master, pushing to this branch should work

@victorivens05 Looks good 👍 I will merge it 🎉
