Wrong detection of FTA changes channel information stored in CardAllocationCache class. When user tries to change channel to another, everything is OK. But when tries to change channel to already seen channel, channel information is get from cache (with wrong FTA state) and TV Server not tune to channel because no CAM is installed.

The channel must have CA section in PMT, but in stream mustn't be any CAT or packets marked as scrambled.

h4. Steps to Reproduce
1. switch to channel which is not FTA (in logs must be message of changing FTA to false)
2. switch to another channel
3. switch to channel in step 1 - you received 'no free cards available' message
