This fix checks if magento is installed before running sheep debug.

[Tickles-BV]

We install sheep-debug as part of our base install, which is all run through composer.

We're running into an issue where if you deploy a new project and try to access it before magento has been installed you get a 500 error instead of the web installer.

This is because replaceProfiler fetches the core_write connection and tries to replace the profiler without checking if magento is installed. This fix adds an extra check in isEnabled in the Data helper to ensure core_write is available.
