* Improve validation when dealing with non-strings

validator@5.0.0+ has stopped coercing input values as strings and since
version 4, the library has been printing deprecation notices everytime a
non-string is passed to it.

All `validate` functions now correctly handle theses cases by delegating
this work to lodash functions.

* Coerce number values when validating

* Remove unneccesary tests checking options object not modified

These tests are now performed universally by the tests support shim

* Tidy tests code
