lite2: store current validator set (#4472)

Browse Source 
Before we were storing trustedHeader (height=1) and trustedNextVals
(height=2).

After this change, we will be storing trustedHeader (height=1) and
trustedVals (height=1). This a) simplifies the code b) fixes #4399
inconsistent pairing issue c) gives a relayer access to the current
validator set #4470.

The only downside is more jumps during bisection. If validator set
changes between trustedHeader and the next header (by 2/3 or more), the
light client will be forced to download the next header and check that
2/3+ signed the transition. But we don't expect validator set change too
much and too often, so it's an acceptable compromise.

Closes #4470 and #4399
