status-go requires some special methods to be exposed in order to support the current integration.
Introduced families of methods marked as `DEPRECATED`:
* `SendRaw` to send transit-encoded messages, both public and private. It supports only private PFS-enabled messages. To send private non-PFS messages, we can add this functionality or it needs to happen through `shh_post` directly from status-react.
* `RetrieveRawAll` and `RetrieveRawWithFilter` to get retrieve decrypted but transit-encoded messages.
* `LoadFilters` and `RemoveFilters` to manage Whisper filters directly.
* By default, persistence of messages is disabled. It can be enabled with an option passed to `Messenger`.
* File paths to the databases are configurable in `Messenger`.
We only generate the bundle once every 6 hours (or if pairing
information changes).
This means that in some cases where many devices appear/disappear,
new devices are not picked up until the bundle is refreshed.
For example:
Alice creates a device with timestamp t1 A1
Alice creates a device with timestamp t2 A2
Alice creates a device with timestamp t3 A3
Alice creates a device with timestamp t4 A4
Alice propagates this to bob, bob's list of active devices for alice is now: t2 A2,
t3 A3, t4 A4 as we only keep maximum 3.
If Alice sends a message to Bob from A1, previously it would be still
using t1 (as long as less than 6 hours have passed).
Now instead the new bundle will have t5 instead, so upon receiving the
message bob will have: t3 A3, t4 A4, t5 A1.
This commit changes the behavior to always update the timestamp before
publishing the bundle, so that as soon as a message is received from a
new device, it will increase the timestamp for that device.
