Added null check for value in getFieldFromDoc in pouchdb selector core utils

[t-cho1]

Sometimes value would be undefined, so in the for loop, it would be looking for value[key], which spits out Cannot read property <property> of undefined

hello @t-cho1 I am terribly sorry for the time that it has taken to get your contribution reviewed. As you have seen, tests has ben migrated to GitHub Actions. I wonder if you can get the latest changes and apply your contribution and check should tests passed?

Thanks.

Hey @t-cho1 , could you rebase from master? It will allow me to trigger Github actions. Thanks!

@t-cho1 @AlbaHerrerias any chance to get this reviewed?
getFieldFromDoc is still crashing whenever the doc is null / undefined

[garethbowen]

@rasgo-cc It seems like @t-cho1 is not responding so nobody can update the PR to run the GH actions which is required to merge. Would you mind creating a new PR from master which this change? Then we can close this one.

Assumption is wrong; this would break pouchdb.
Since it needs more work and the author isn't active, I suggest to abandon this patch.
