Fix Get-WinEvent -FilterHashtable to work with named event data field
Now FilterHashtable parameter in Get-WinEvent for named data field:
1. generates a valid query, ex. @{Logname="System";Param="a"}
2. generates a valid query for multiple values, ex.
@{Logname="System";Param="a","b"}
Also removed double cast in the original code and added more tests to cover the fixed scenarios.
