New session ID is not created

SDK version: 1.4.4

A new session ID is not provided even after the minTimeBetweenSessionsMillis is exceeded. The issue only happens when there is an ampli.identify() call at app start. In this case `startNewSessionIfNeeded` is called twice causing probably some threading issue. When I only put a breakpoint inside `isWithinMinTimeBetweenSessions` I get `timestamp - lastEventTime == 0`. If I start debugging I can also get a negative number for `timestamp - lastEventTime`

I can see that once the function is called from `onEnterForeground` and the other time it is called because of `applyContextData` inside `AndroidContextPlugin` because of the identify call. Probably this is causing a threading issue.

With this I can reproduce the issue:
```
ampli.load(
context,
LoadOptions(
environment = Ampli.Environment.DEVELOPMENT,
client = LoadClientOptions(instance = Amplitude(Configuration(apiKey = apiKey, context = context, minTimeBetweenSessionsMillis = 5000)))
)
)
ampli.identify(null, Identify(property ="value"))
```

Once the identify is removed then it works fine.
