`getLogs` for multiple accounts simultaneously. For now only used for
new transfers detection. Detection of `new` transfers has been changed,
now they are searched from head and forward. Previously they were
searched from last scanned block forward.
Balance history was not checked for all chains if no history on
some chain.
Removed `SetInitialRange` from wallet API as internal implementation.
This method was called on adding a brand new Status account to initialize
blocks_range table to avoid transfers history checks.
- reverted a change that stopped looking for ERC20 transfers if no nonce
and balance change found within a block range for ETH
- implemented sending EventRecentHistoryReady event at a proper time
- moved EventFetchingRecentHistory event to Strategy type as it does not make
sense to send this event in loop
- moved iterating through blocks logic to inside of `loadTransfers` command, which
now accepts a block range.
- reuse `uniqueHeaders` function in commands.go
- clean up

strategies.
On mobile devices we might not want to load all transfers history
to avoid high internet traffic consumption or to save some space.
On desktop we will load all transfers in background.
- Moved current fetching transfers implementation to
OnDemandFetchStrategy
- Implemented QueuedAtomicGroup to cache outgoing commands above a
threshold
- Refactored some type names, methods for better clarity:
- LastKnownBlock name was misused
- Block renamed to BlockDAO to clarify what it does and avoid
confusion with geth Block type
- Cleanup - removed unused parameters and types' members
- Changed tests to use in memory DB for speedup
- Added more logging and comments
