Before the result is filtered by empty-trim check, so the trim will not be affected to original array

Why do we need to apply trim to the original array? What issues happen if we do not apply the trim?

I'd like to avoid doing double mapping here if not necessary. If we get entries that needs to be trimmed we can do that on another place where we already map out the results.

In Cassandra, the received output has leading and trialing spaces, so the keyspaces and tables are not mapped at all if not trimmed.

We can also iterate the dictionary and trim but trimming while splitting result seems easy for me. We can move the trimming part to another variable below the "mapped" variable.

I checked if there is maybe a faster way to do it but it seems that using map and filter is the most performant.
I think this will be good to go oncetpope/vim-dadbod#148 is merged
