## Description
### Cause of issue
Appsmith's persistent data is stored in the browser's localStorage under
a key generated using the `applicationId` and `branch name`. When
fetching the store's value on page load, if the branch's name is not
present in the URL string, its value defaults to an emptyString.
### Solution
Default value of `branch name` should be the current git branch.
Fixes#15692
