Sync demo app from OS X bundle crashed on first login

[austinzheng]

I downloaded the OS X bundle, started the server, and opened the prebuilt copy of RealmTasks. Then I made a new account and pressed the log in button.

The app crashed with the following error:

Application Specific Information:
terminating with uncaught exception of type realm::RealmFileException: Unable to open a realm at path '/Users/austinzheng/Library/Application Support/io.realm.realmtasks.macos/realm-object-server/io.realm.object-server-metadata/sync_metadata.realm.management': make_dir() failed: No such file or directory.

This is really weird, because:

• The base URL (/Users/austinzheng/Library/Application Support/io.realm.realmtasks.macos) is provided by one of our APIs in RLMUtil.mm and itself is based on a well-known directory provided by the OS.
• All the intermediate directories should be created by the NSFileManager APIs.
• On the subsequent launch the directories were created properly and the app worked fine.

This is a bad user experience and I want to look into this issue more carefully.

@austinzheng did you launch an app before starting the server? Currently there is a workaround in .start-object-server.command that removes this files:

if [ ! -f "$package/object-server/installed" ]; then
    echo "Deleting files from the previous version"
    rm -rf ~/Library/Containers/io.realm.{RealmTasks,realmbrowser,realmtasks.macos}
    ...

This should be removed after #205 is implemented.

Yeah, I did. Okay, that makes sense then. Thanks! (Also explains why I couldn't reproduce it...)
