fixed dependencies issue

[Yash621]

This PR is with respect to issue #132

In package.json we have to update the version of react-native from 0.58.6 to 0.60.6 otherwise react-native-fbsdk throws dependencies issues.

Likewise we have to upgrade the version of react from 16.12.0 to 16.8.6 to make npm install work.

@shehand Please review it and let me know if any changes are required.

@Yash621, can you verify that with this change the app will still work? We had an issue in map component where it actually did not work on RN > 0.58

@shehand can you look into this issue #131 ,without making these changes I was unable to run the app, but after doing these changes I am running in the issue #131 .

@Yash621, upgrading the modules to latest is a must that we should do and I have no issue with it. I was wondering whether with this upgrade other components need to be updated too. There might be small chance that there are other dependencies that should be updated along with this other than just updating RN and React. And regarding the mentioned issue, there is no enough information. Could you just add more info(something like the debug log) to the issue so that we can ensure this dependency upgrade is a must that should be done at this moment.

@shehand I have fixed that issue by downgrading react-native version to ^0.60.0.
after that I ran into this issue #134 ,but I fixed it, and also have posted a solution of it in this issue #134 ,so that it could be helpful for others

Why was Unnecessary Dependency added?

I am not sure about the reason, but don't worry I will revert that :)
Ps: I am digging deep into the issues faced by all the other students as many students are facing a lot of issues while setting up the project, and will make a guide soon for all the errors and their solutions :)
