In #67, the `isFlagSet` logic was changed so that it always returned true, so even unmentioned flags would override previously set values. This PR fixes that issue (fixes #79) and also changes the flag tests to be somewhat more flexible and test this specific issue. I haven't made any wider fixes because the concept of using command-line flags as a backend is fundamentally broken in a way that cannot be fixed (see #63), so will probably be removed in a future major version release of confita.
