ResetIncrState before all other track_event packets

While adding support for timestamp delta encoding, we realised that
first packet coming from track_event data source could be something
different from `ResetIncrementalState`. Which can cause problems.

For example, see line 87 in  https://www.diffchecker.com/gKUL1x4J

As we are dropping the explicit `timestamp_clock_id` field from each
packet and utilising it's value from `trace_packet_defaults`, it's very
important to ensure that a packet which sets correct default values in
`trace_packet_defaults` comes before any other packets.
