Variable and String token fix

Variable token fix: Some variables were being obfuscated without trimming out double quotes (i.e. ${"var`Name"} instead of ${varName})

String token fix: ParameterSetName strings (but not DefaultParameterSetName) string values now error when trying to concatenate or reorder even when encapsulated with curly braces. This fix downgrades these parameter binding scenarios with double quotes and tick markes, same as a member token obfuscation. This was causing errors when obfuscating, for example, Invoke-Mimikatz with any kind of STRING token obfuscation (Token\String\* or Token\All\1).
