Describe the bug
request to /example requests http://localhost/example

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/Ribesg/Kita/tree/2c7941183ebcde1fc2193bd00a1bed53f1249b10 on a machine which can be reached from the network (a server)

   git clone https://github.com/Ribesg/Kita
   cd Kita
   git reset --hard 2c7941183ebcde1fc2193bd00a1bed53f1249b10
   

2. Run ./runServer.sh
3. Browse to https://yourserver:12345
4. Try to login using whatever credentials (correct ones are admin/admin)
5. See failing requests to https://localhost/api/auth/login instead of https://yourserver:12345/api/auth/login in the console

Expected behavior
Requests should use the current location.origin when none is provided in the browser
