Issue with version 3.0.0

After updating to Version 3.0.0 of the capacitor plugin, I always get the following error:

Serious error executing plugin

I adjusted my app like mentioned in the Android setup: https://github.com/BranchMetrics/capacitor-branch-deep-links#android-setup

After adding

activity = getActivity();

to BranchDeepLinks.java it works again

It could probably happen when calling one or more of the following methods: showShareSheet, generateShortUrl and sendBranchEvent. These methods do not necessarily make sure to instantiate the activity variable.

It is because of this commit: 0dbd399#diff-7dcd608548c6c4277db3aa21fca44b202ff712b42548c381870ce930e3262659

You can see this.activity = getActivity(); has been deleted. So adding that will indeed fix the issue. Feel free to make a pull request for this. Branch will probably merge it sometime in the future.
