config: fix bug in walletrpc interaction due to mismatched coin type

Browse Source 
In this commit, we fix a bug that would cause the walletrpc on the
simnet chain to not be able to respond to all RPC calls. The issue is
that for the SimNet backend, within chainparams.go:
6e0a67d05b/chainreg/chainparams.go (L45-L51),
we set a new CoinType for Simnet in order to match the RegTest value.

Later on, when we go to verify the on disk accounts against the
in-memory cointype, we fall through to an error case as the in-memory
cointype is 115, while the on disk cointype is 1.

To fix this, when we know we're doing simnet mode, we'll override the
cointype similar to the way we did/do for LTC.

Fixes https://github.com/lightningnetwork/lnd/issues/6807.
