Fix ItemMetaData() crash

[cewert]

It's possible for data.type to be invalid. Remove LCase() function call causing the crash instead of refactoring. Comes from roku.com crash log:

Type Mismatch. (runtime error &h18) in pkg:/source/api/Items.brs(103) 
Backtrace:

which points to this line after running build-prod on 2.1.2:

else if LCase(data.type) = "recording"
