My Jetpack: Activate plugins in normal mode

[leogermani]

Changes proposed in this Pull Request:

• Do not use Silent mode when activating plugins from My Jetpack.

This was done to avoid errors caused by the redirects, but now plugins won't redirect by default and it's safe to activate in normal mode.

This way we trigger the activated_plugin hook and make sure plugins are properly activated

Other information:

• Have you written new tests for your changes, if applicable?
• Have you checked the E2E test CI results, and verified that your changes do not break them?
