No Data available in access frequencies and configurations

[Alexander-Dubrawski]

Please describe the bug:
If we navigate to the access frequencies and configurations graph we are not able to see the data. Moreover after a reload and a switch between the comparison and overview page some tables can't be selected anymore.

Please describe steps to reproduce:

1. Add a database
2. Load a workload
3. Click on comparison
4. Scroll down to Segment Access Frequencies
5. try to select a table
6. See the message that no data is available

What is the expected behavior? Please describe:
We should be able to select the tables

Screenshot(s):

Possible source of error:
The list of available tables is used by the Access and Segmentation component from the meta/components.

Cockpit/hyrisecockpit/frontend/src/components/metrics/Access.vue

Line 41 in e7f8068

:items="selectionItems"

Cockpit/hyrisecockpit/frontend/src/components/metrics/Access.vue

Line 84 in e7f8068

import { useDataWithSelection, UseDataWithSelection } from "@/meta/components";

Cockpit/hyrisecockpit/frontend/src/meta/components.ts

Line 93 in 8c57dd6

export function useDataWithSelection<T>(

There we are getting the information from the meta/database.

Cockpit/hyrisecockpit/frontend/src/meta/components.ts

Line 101 in 8c57dd6

const { databases } = useUpdatingDatabases(props, context);

This module is getting its information from the database controller:

Cockpit/hyrisecockpit/frontend/src/meta/databases.ts

Line 10 in 8c57dd6

context.root.$databaseController.getDatabasesByIds(

The table information is returned in:

Cockpit/hyrisecockpit/frontend/src/controller/databaseController.ts

Line 96 in 8c57dd6

tables: storageInformation!.tables,

Maybe the problem has something to do with the reactiv method from the vue composition api.

Cockpit/hyrisecockpit/frontend/src/controller/databaseController.ts

Line 10 in 8c57dd6

import { ref, reactive, computed } from "@vue/composition-api";

or the controller is just not up to date.

Additional context:
The problem seems to be in the frontend if we manually reload the page we can select the tables.
