Wrong fix on RECS0063 with StartsWith

[Thieum]

Having this code:

query.StartsWith("select", true, CultureInfo.InvariantCulture)

RefactoringEssentials will pop a RECS0063, despite the fact that we are using Invariant Culture.

When using the fix provided, the code be will be changed to

query.StartsWith("select", true, CultureInfo.InvariantCulture, StringComparison.Ordinal)

which is not a valid call of StartsWith:

        public bool StartsWith(String value, StringComparison comparisonType);

        public bool StartsWith(String value, bool ignoreCase, CultureInfo culture);

        public bool StartsWith(String value);

We should either detect that we don't need the refactoring as we are already using InvariantCulture or switch to the String comparison version of the method.
