Fix event forwarding

[nimau]

This PR fixes #7641 There were two issues:

• The ShareManager was using a specific session and store.
• The MXRoom, during its initialization, resets the timestamp of outgoing messages.

The fix is in two parts:

• ShareManager can now be used with a specific session (in this case, message forwarding is done inside the application and not using a share extension, so using the current session seems fine).
• The corresponding room summary is reset once the message has been sent (to take account of the fact that it may have been created with an incorrect timestamp).
