refs:cf514cdf7- in commitcf514cdf7we moved the loadSettings call up to the bridge - here we can call the async method, so we can remove loadSettingsSync altogether - all the tests have now been changed to use the async method

/**
|
|
* The Bridge
|
|
*
|
|
* The bridge is responsible for handing communication from the server to the frontend.
|
|
* Data should only be flowing server -> frontend.
|
|
* As the architecture improves, the number of cross requires here should go down
|
|
* Eventually, the aim is to make this a component that is initialized on boot and is either handed to or actively creates the frontend, if the frontend is desired.
|
|
*
|
|
* This file is a great place for all the cross-component event handling in lieu of refactoring
|
|
* NOTE: You may require anything from shared, the frontend or server here - it is the one place (other than boot) that is allowed :)
