In this commit, we fix a race in the `TestPackager` series on channeldb.
A few tests were sharing the same global variable of the set of log
updates, which includes a pointer to an HTLC. The `ExtraData` value of
the HTLC would then be mutated once we go to encode the message on disk.
To fix this, we the global with a function that returns a new instance
of all the test data.

==================
```
In this commit, we fix an inconsistent in the API related to AMP
payments. When a payment request isn't specified, we require the `--amp`
flag on the CLI to make an AMP payment. However, for payment requests,
we don't require this flag. To fix this inconsistency, we now require
the `--amp` flag to _also_ be set for payment requests.
This commit changes how we transform from a deadline option to a
concrete deadline value - previously this is done when we decide to
cluster inputs, and we now move it to a step earlier - once an input is
received via `SweeperInput`, we will immediately transform its optional
deadline into a real value. For inputs that come with a deadline option,
since the Some will be used, it makes no difference. For inputs with
None as their deadlines, we need this change to make sure the default
deadlines are assigned accurately.
