[Reporting] Fix check for security and added jest test

[jloleysens]

Summary

Per the issue reported here: #108774. This contribution fixes a check for whether security is available and adds a test to confirm the expected behaviour. This brings the check in line with other places in Kibana like:

kibana/x-pack/plugins/ingest_pipelines/server/plugin.ts

Line 40 in ca6bb4b

isSecurityEnabled: () => security !== undefined && security.license.isEnabled(),

How to test

This is a little bit tricky to test, since the code for throwing the ES error is only on 7.x branches and relates to a very specific state of licensing (trial without security enabled).

On the reported issue (#108774), this can be tested by downloading the linked snapshots and editing the javascript directly (adding the security.license.isEnabled() to the if statement).

1. Start Kibana & ES
2. Ensure that trial license is active
3. Navigate to the Reporting Management UI
4. Check the Kibana terminal for Internal Server Error (should be clear with the fix applied)
