adding a check for the sticky regExp option supported by Firefox and …

…accepted by the ES6. Note that the tests for this case are checking for the support of the sticky parameter. the logic is still tested by the other expect statements in browsers that do not support sticky but will never enter that block as creating a regExp with that flag is not allowed. Coverage is still good. See #234
