SECORE exception when mandatory parameter is missing

[Piero Campalani]

Although SECORE throws exception when you don't provide a mandatory parameter (authority|version|code) in a KVP URI, it returns a misleading exception:

​http://localhost:8080/def/crs?authority=EPSG&version=0

<ows:ExceptionText>Operation not defined</ows:ExceptionText>

Like is done in this example (which in turn maybe should better alert that foo is an illegal parameter):

​http://localhost:8080/def/crs?authority=EPSG&version=0&foo=4327

<ows:ExceptionText>Insufficient parameters provided</ows:ExceptionText>

I fixed the first case, but that foo is an illegal parameter is not possible as there's no distinction for parameterized CRS.
