Crashlytics reporting a crash when the user lost the internet connection

[revtut]

Hi everyone,

When the enableAnalytics is enabled if the user had the app opened but out of the sudden lost the internet connection, the syncing method will throw an error that is not caught anywhere and thus reports a crash.

I believe that we should not throw the error and instead just log it. What do you think about it?

In the meantime, I'll disable the analytics to avoid any crashes.

throw FlagsmithApiException(e);

@revtut This makes sense to me - it would be consistent with what we're doing already for other SDKs. For example:

• Node.js: https://github.com/Flagsmith/flagsmith-nodejs-client/blob/a2a3c1c997b5f9a7478627ae7029577667fc6555/sdk/analytics.ts#L54-L58
• Java: https://github.com/Flagsmith/flagsmith-java-client/blob/9f506f41007b21b7f0a90dcaa12069a7245fe581/src/main/java/com/flagsmith/threads/AnalyticsProcessor.java#L127-L135
• Android: https://github.com/Flagsmith/flagsmith-kotlin-android-client/blob/c49f0884eea59775e6ce4395bd05a2ce3f45d7df/FlagsmithClient/src/main/java/com/flagsmith/internal/FlagsmithAnalytics.kt#L25-L30

Not all SDKs do this but it does seem like a reasonable default. @revtut would you be okay to send us a PR for this?
