stagingBin.minifyBin (true) not working for Nodejs 10 & 11

[marcelobern]

stagingBin.minifyBin (true) throws:

Error: ENOENT, no such file or directory '/home/travis/.local/share/Trash/files'

Problem seems to be related to trash, so opened issue.

Issue ended up being on mock-fs, to added a toggle in the test cases to use integration/mock tests to be able to bypass the mock-fs Nodejs 10 & 11 issues.

This issue is fixed in PR #2.
