Update user-profile app scripts

1. UserProfileDemo project links the CouchbaseLiteSwift from `example/iOS/CouchbaseLiteSwift.framework` we should either:

use the same path, and remove `cd Frameworks` from the script.

move to the Frameworks folder, which is more cleaner.

2. Optional, in order to execute the script from a different current directory, use this. For e.g., Issue will happen, if you execute the install_12.sh script from one folder back.

```

PARENT_PATH=$( cd "$(dirname "${BASH_SOURCE[0]}")" ; pwd -P )

pushd $PARENT_PATH

// script code!!

popd

```
