Update function settings to recreate Variable modal with correct selectedVar

[stnguyen90]

What does this PR do?

It seems the Variable's selectedVar was always null when updating a variable. This update makes the Variable match the wizard:

console/src/routes/console/project-[project]/functions/wizard/step5.svelte

Lines 114 to 120 in d0c5079

	{#if showCreate}
	<Create
	bind:selectedVar
	bind:showCreate
	on:created={handleCreated}
	on:updated={handleUpdated} />
	{/if}

to ensure the correct selectedVar is passed.

There is also a bug here were you can't create a variable after attempting to update a variable, but that should be fixed by:
