With Cobra 1.0, it is now possible to control when file completion
should or should not be done. For example:
helm list <TAB>
should not trigger file completion since 'helm list' does not accept
any arguments.
This commit disables file completion when appropriate and adds tests to
verify that file completion is properly disabled.

Before this change, running 'helm env' multiple times would generate
a different order for the output each time. This is because Go
purposely loops over hash maps in a random order.
This commit sorts the environment variables by alphabetical order before
generating the output.
