tracker issue : CF-4202905

Note: In ColdFusion, all simple values can be treated/validated as a string. A UDF string argument accepts a date. IsValid("string", now()) returns true. Etc, etc.

Issue: ArrayFindNoCase denies some strings

Repro 1:

ArrayFindAllNoCase/ArrayContainsNoCase/ArrayDelete accept any string, including date (good)
{code:java}
<cfscript>
  myArray=[]
  writeOutput(arrayFind(myArray, now()))//0
  writeOutput(arrayLen(arrayFindAll(myArray, now())))//0
  writeOutput(arrayContains(myArray, now()))//NO
  writeOutput(arrayDelete(myArray, now()))//NO
  writeOutput(arrayLen(arrayFindAllNoCase(myArray, now())))//0
  writeOutput(arrayContainsNoCase(myArray, now()))//NO
  writeOutput(arrayDeleteNoCase(myArray, now()))//NO
</cfscript>
{code}

Actual and Expected Result: 00NONO0NONO

Repro 2:
ArrayFindNoCase denies dates (bad)
{code:java}
<cfscript>
  myArray=[]
  writeOutput(arrayFindNoCase(myArray, now()))//exception
</cfscript>
{code}

Actual Result: exception "Valid datatype for element to search is String."

Expected Result: 0

Basically, in the following, arrayFindNoCase() must never throw an exception when a date is passed to the myString argument and thru isValid("string", ..):
{code:java}
<cfscript>
  function f(required array myArray=[], required string myString) {
    if(isValid("string", myString)) {
      writeOutput(arrayFindNoCase(myArray, myString))
    }
  }
</cfscript>
{code}
