Max Leiter dc7f79fe92 sqlite: add message history index (#5107) ...

Fixes #5103

Today, `getMessages()` filters by `(network, channel)` but sorts by
`time DESC, id DESC` and no index covers both (and a new one supersedes
`network_channel`). This has always been an issue but
https://github.com/thelounge/thelounge/pull/5055 made this code
synchronous which exposed it.

|  | Before | After |
|--------|--------|--------|
| history load, 5 channels (4.4M rows total, busiest 3M) | 6.9s, event
loop blocked | 80ms |
| single channel with 3M messages | 4.6s | 18ms |
| query plan | index scan + temp B-tree sort | index only |
