Mempool import fails

[kallewoof]

Describe the issue

When stopping Elements (regtest) using ^C, after restarting it, mempool transactions will fail to import (possibly because a lot of them are chained and depend on each other).

Expected behaviour

A ^C shutdown followed by a restart should not fail to import any mempool transactions.

Actual behaviour

A restart results in a failure to import some/all mempool transactions.

Any extra information that might be useful in the debugging process.

Can confirm the issue, getting the issue when mempool is larger than 1.

[instagibbs]

It seems to just be a race between the wallet re-submitting the transaction successfully and being loaded from the mempool cache from disk(not a bug). Can you make sure that your mempool is actually empty?
