Allow Type Checking Functions to Accept Null Values in Partial Null Support

Description

Currently if we check for example:

isArray(noSuchVariables) isBoolean(noSuchVariables) isQuery(noSuchVariables)

etc., we get an error that the variable does not exist.

A much better return value would be a simple `false`, since the value passed into isXxx() is not Xxx. We can already check isNull(noSuchVariables), so we should be able to similarly pass noSuchVariables into the ixXxx().

Why do we need to check !isNull(noSuchVariables) && isXxx(noSuchVariables)? If the question is isXxx() and the value is null, then the answer is false, which is exactly what isNull(noSuchVariables) returns.

this would break a lot of existing code, but i agree that this would be a nice addition. so it should not work out of the box that way.
