excludeRegex not excluding files

[l1b3r]

This is a (Bug Report / Feature Proposal)

Description

For bug reports:

• What went wrong?
  When running sls package --verbose, excludeRegex option added in v5.4.0 seems to be ignoring the regex and still adds all files to the output zip files.

• What did you expect should have happened?
  Files that match excludeRegex should be excluded from the packaged zip files.

• What was the config you used?

webpack: {
            keepOutputDirectory: true,
            excludeRegex: /\.ts|test|\.map/
        }

(I'm using serverless.ts instead of serverless.yml but that shouldn't matter I believe)

• What stacktrace or error message from your provider did you see?
  sls package --verbose does not throw any explicit errors.

For feature proposals:

• What is the use case that should be solved. The more detail you describe this in the easier it is to understand for us.
• If there is additional config how would it look

Similar or dependent issue(s):

• Initial implementation

not working, just debug into packageModules.js where files in filters, but not passed into the zip args.
