Don't show unsaved changes warning modal after table creation

Fixes: #1925

Hey! Thanks for submitting this code. I think this is a great addition, but I think we should make one change to the API you are introducing.

Instead of passing an action to the close function, I think it'd be good if instead it was an optional object. This way it's a general purpose feature that any tab can use.

Something like:

this.$root.$emit(AppEvent.closeTab, this.tabId, { ignoreUnsavedChanges: true })

Then the close signature is something like:

interface CloseTabOptions {
  ignoreUnsavedChanges?: boolean
}
async close(tab: OpenTab, options?: CloseTabOptions) {...}

Hi @rathboma !
Thanks for the review. Yeah that make sense. I have made some changes for that.

I was also thinking about maybe adding the tabId property also to that options object
but for now I just added ignoreUnsavedChanges property only in there 😄

Thanks so much!
