test: remove unnecessary BlockContext wrapper from TopBar CurrentTask test

Remove legacy BlockContext.Provider wrapper that is no longer needed.

CurrentTask component was migrated to use cn() helper and no longer uses
BlockContext internally (no useContext or useBEM calls), so the context
wrapper in tests is unnecessary.

Changes:
- Removed BlockContext import
- Removed all BlockContext.Provider wrappers around component renders
- Tests still pass - component doesn't consume the context

This cleanup allows us to potentially remove BlockContext from bem.ts exports.
