Change Nci to CellInfo.UNAVAILABLE_LONG

Problem:
CellInfoTest#testCellInfo fail
Root cause:
In CellIdentityNr.sanitizeLocationInfo, Nci is set to CellInfo.UNAVAILABLE
But in test case, CellInfo.UNAVAILABLE_LONG is expected
Solution:
Change Nci to CellInfo.UNAVAILABLE_LONG in CellIdentityNr.sanitizeLocationInfo
