Merged in fixes to OffsetDateTime by SamiKouatli. Fixed Andorid API'a before 26.

[tkeithblack]

I pulled this change from SamiKouatli's fork and have been using it for a bit over two months in a non-production product. It solved the pre-API 26 issue for me. I am submitting the pull request for consideration, however, I am not an expert in this area and cannot guarantee its effectiveness at all API levels. Feedback is appreciated.

Quoted from SamiKouatli's checkin:
OffsetDateTime is available only for sdk version > 26
This modification allows us to use the plugin with older version of Android. However it might not be the clean and proper way to do it.

This change was included in the 0.5.4 release.

Awesome, thanks!

I'm looking further at it, and wondering why the PR used Instant. I'm not familiar with the specifics of Android versions, but Instant is a part of the java8 time spec, like OffsetDateTime. Are you saying it works for you like this?

@ericmartineau,

I have used this from my own fork on both Android API 24 & 28. It runs without errors and allows querying of contacts. However, I have very limited testing thus I'm not in a position to say it works w/o issues. Sorry I can't be of more help.

[ericmartineau]

Either way, I introduced joda-time and got rid of the reference to Instant - I'm guessing it would've caused some issues.

Thanks, I'll pull it and give it a try!
