Null check pinned messages after decryption when filling PinnedMessageModel.

Browse Source 
`room()->decryptMessage()` returns null if the message fails to decode. Since elements of `m_pinnedEvents`
get directly dereferenced in getEventForIndex, storing null values leads to a segfault.
In this case we should retain the EncryptedEvent to let the UI report the error.
