Fix context inside 'with reverse block' that weren't executing
Fix context inside 'with reverse block' that weren't executing

Contexts named
 * using EKMappingBlocks
 * using mapping blocks with nil value

weren't executing beause the `should` clauses inside of them were
written outside of the `specify` blocks.
Fixed.
Had to modify "when male" context as well as I moved its `beforeEach`
block up.
