btcwallet 0.13 wtxmgr go.mod require needs update

The tagged btcwallet v0.13.0 currently specifies wtxmgr v1.3.0 in the go.mod, however a newer revision of wtxmgr that has the InsertTxCheckIfExists method is actually required. A consumer must add a replace to their project's go.mod if they wish to use btcwallet v0.13.0. e.g.

github.com/btcsuite/btcwallet/wtxmgr v1.3.1-0.20211113022102-559f6eff0e52

Consumers can work around this as above, but perhaps a tag and updated require is something for the next patch release. I find that when tagging releases, that removing replace statements is helpful to smoke out such things, however minor they are.

Alternatively, btcwallet might consider removing wtxmgr as a standalone module, in favor of absorbing it into the main module. I'm not familiar with use cases for wtxmgr that might be sensible without the root module in use as well.

Specifically, I guess I'm requesting:

• a wtxmgr/v1.4.0 tag
• updated go.mod so the main btcwallet module uses that
• a v0.13.1 tag for the main btcwallet module, preferably at a revision with replace statements removed to confirm the requires are sufficient

I'm eager to update to v0.13, but it is somewhat awkward to need a replace or require to hoist the wtxmgr module to a newer untagged revision.

Thanks! The 0.13 change list looks really nice. In particular I'm curious about if and how 34da5cf affects peering for light clients.
