chore(dataset): enable reload for schema and table

[justinpark]

SUMMARY

long history but schema and table selector isn't enabled the reload feature when Dataset creation modal implemented.

Due to the cached dataset, user cannot create a new dataset using "Add dataset" modal when a new table recently added. In order to do so, user must hit the refresh request on sqllab page and then reload the modal again.

This commit enables the refresh button for formMode (which is only used on DatasetModal) in order to reduce the UX inconvenience.
