After a successful "Save copy as" operation, the next save copy as operation will re-use the previous target directory as its base directory in the "save as" dialog in the 'directory' path editing widget. The list widget below, supposed to show the content of this directory (files contained) still shows the current PDF file's directory's location

Reproducible: Always

Steps to Reproduce:
1. Create temporary directories /tmp/A and /tmp/B
2. Create example PDF files /tmp/A/a.pdf and /tmp/A/b.pdf
3. Open /tmp/A/a.pdf in Okular
4. "Save Copy as" this file as /tmp/B/a.pdf
5. Issue "Save Copy as" a second time to get a "Save as" dialog again. Observe that the path editing widget shows "/tmp/B" (last location of a successful "save copy as" operation), whereas the file list widget below shows the content of "/tmp/A" (the current location of the currently open directory), as you will see both a.pdf and b.pdf (the latter does not exist in /tmp/B).
