Improper encoding of redirect locations

[nitram84]

If a persistent identifier or a filename contains a space character, invalid redirection locations are returned. Redirections with invalid location URIs are causing problems with http clients like org.apache.httpcomponents:httpclient:4.5.*

Steps to reproduce:

Case 1: Space character in filename

https://viewer.goobi.io/viewer/content/PPN407465633d27352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/800/0/00%20000001.tif

First redirect: 301 Location: https://viewer.goobi.io/content/PPN407465633d27352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/800/0/00%20000001.tif (ok)

Second redirect: 302 Location: https://viewer.goobi.io/api/v1/records/PPN407465633d27352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/files/images/00 000001/full/800,/0/default.tif (invalid)
Expected: Location: https://viewer.goobi.io/api/v1/records/PPN407465633d27352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/files/images/00%20000001/full/800,/0/default.tif

The result is: {"status":404,"message":"Image source not found: /opt/digiverso/viewer/data/2/media/PPN407465633d27352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/00 000001"}

Status is ok (I tried to fetch a non existing image.), but sending a full path is information disclosure and should be fixed too.

Case 2: Space character in persistent identifier

First redirect: 301 Location: https://viewer.goobi.io/content/PPN407465633d2%207352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/800/0/00000001.tif (ok)

Second redirect: 302 Location: https://viewer.goobi.io/api/v1/records/PPN407465633d2 7352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/files/images/00000001/full/800,/0/default.tif (invalid)
Expected: Location: https://viewer.goobi.io/api/v1/records/PPN407465633d2%207352e322e27_40636c6173736e756d3d2733322e27_407369673d2733322f303827/files/images/00000001/full/800,/0/default.tif

The result is HTTP Status 500 – Internal Server Error. I would expect a 404 status here.
