Changing from a light theme to a dark theme does not update selected database icon

[henrymercer]

Describe the bug
When the current theme in VS Code is changed from a light theme to a dark theme, the icon used for the selected database remains as the light theme icon. It should instead change to the dark theme icon.

To Reproduce

1. Select a light theme in VS Code
2. Reload the current VS Code window
3. Select a database
4. Observe that the light theme "database selected" icon appears next to the database
5. Change the current theme in VS Code to a dark theme
6. Observe that the icon next to the database is still the light theme icon.

Expected behavior
After step 5 above, the database selected icon should be updated to the dark theme icon.

This seems to have been an transient issue, repro steps no longer work on a fresh instance of VS Code.
