S5 General Improvements

[nialexsan]

Description:

1. In ERC4626PriceOracles in the init() function, the verification for assetEVMAddress has already been
   assured by a previous assert statement, and the value could be cached.
2. In ERC4626SinkConnectors , the _call function is never called with dry = true , therefore the function can be simplified.
   Further, the natspec is inaccurately assertaining that only drycalls are done.
3. In EVMNativeFLOWConnectors.Sink , the typechecks in depositCapacity() are already guaranteed by the inherited
   preconditions.
4. In EVMTokenConnectors.Sink , the typechecks in depositCapacity() are already guaranteed by the inherited
   preconditions.
5. In UniswapV3SwapConnectors.Swapper , the getPoolAddress() function always returns the pool for the first hop in the
   default direction. If the swapper contains a multi-hop path, this may be misleading. Adapt the function to accept a hopIndex
   and reverse flag.
