Reset the lastUsedChannels on a gridstorage change

Previously it did encode the current and previous used channels into the
same as well as mask it with 0xFF. Which lead to an overflow every 256
gridnodes requiring a channel. This will not happen at > 2^31

Also removes the need to bitshift them for every access.

Fixes #1510
