All issue types migrated every time a migration is run

Issue Summary

When migrating projects with Jira Cloud Migration Assistant, the plugin should only migrate entities related to the selected projects. This also means that only the Issue Types referenced in these project workflows should be migrated when a given project is selected. Currently, all migrations with the migration assistant are bringing over all Issue types' each time any migration is ran which can create duplicates on the target.

Steps to Reproduce

1. Create a specific issue type and associated it with a non-migrating project
2. Install Jira Cloud Migration Assistant and migrate a project that doesn't have the issue type from step 1

Expected Results

Only the issue types associated with selected projects will be migrated.

Actual Results

All issue types are migrated with any run of Jira Cloud Migration Assistant whether the selected project includes them or not.

Workaround

Delete the excessive issue types that are not required in post migration.
