### Please describe the problem.

In recent version of git-annex (including the most recent standalone version), uploading to box is slow. Typically, it will take 25 seconds or so for git-annex to begin the upload, whereas with previous versions it happened almost instantly.

I used git bisect and rebuilds via stack to locate the commit that introduced this problem. This was the result:

     Bisecting: 0 revisions left to test after this (roughly 0 steps)
     [cf51f40f0eaed2c5968f35b94bebab4a1c819491] webdav: Changed path used on webdav server for temporary files.

Please note: this is distinct from the bug I reported here (https://git-annex.branchable.com/bugs/git-annex_can_no_longer_copy_files_to_box/), since it also affects the standalone version.

### What steps will reproduce the problem?

Use a version of git annex built after the commit above from Sept. 15 (e.g., a recent standalone):

Use a repo with a box remote set up with encryption and chunking:

     WEBDAV_USERNAME=[username] WEBDAV_PASSWORD=[passwd] git annex initremote box type=webdav url=https://dav.box.com/dav/mystuff/annex chunk=100mb keyid=[keyid]

     echo "Hello, world!" > test.txt
     git add test.txt
     git annex --verbose --debug copy -t box test.txt

### What version of git-annex are you using? On what operating system?

Tested with the nightly standalone build on arch linux:

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes! Thank you!
