fix(dashboard): load charts correctly
-->
### SUMMARY
<!--- Describe the change below, including rationale and design decisions -->
Users are blocked when trying to save a dataset on a query/table that has an ARRAY column in it. Due the python_type returning a list instead of a str for the type. To fix this i've added a util function to check if the type is a list and convert it to a string like this `ARRAY`

I agree, using the original native type is the ideal solution here.

I'm pretty sure it was still ARRAY, but this is only a patch i'm pretty sure there other types we'd have to map to strings later

Can it also be a `STRUCT`? I guess it probably depends on the database.
