Fix sorting of versions containing hyphens

[PHPirates]

Pull Request Details

• Fix compareTo for versions that have equal major, minor and patch versions and both contain a hyphen

Description

Assume that if all major, minor and patch versions are the same, a version with a hyphen is older than a version without one.

Related Issue

Fix #171

Motivation and Context

When two versions e.g. 0.9.5-alpha.3 and 0.9.5-alpha.4 both contained a hyphen, the compareTo always returned -1 no matter which was left or right.
This violates the compareTo contract, causing issues like #171.

How Has This Been Tested

If I put the full changelog from here in the test then I reproduce #171. Unfortunately I did not manage to create a minimal test for this, but with this change for me the issue is fixed.
