### Please describe the problem.
git-annex-view fails with an error message that `viewindex.lock` exists and another git process is running in the repository.
The problem appears even with newly initialized repositories.
### What steps will reproduce the problem?
The steps I followed to reproduce the problem:
[[!format sh """
cd /tmp
mkdir testgit
cd testgit
git init
git annex init
echo 123 > test1
echo 456 > test2
git annex add test1 test2
git commit -m 'initial commit'
git annex metadata -s test=test1 test1
git annex metadata -s test=test2 test2
git annex view test=test1
"""]]
Note: The problem does not appear with git-annex version 7.20190819+git2-g908476a9b-1~ndall+1 but it appears with 8.20201007-g903b2f1.
### What version of git-annex are you using? On what operating system?
I could reproduce the problem at two different machines, both with Ubuntu 18.04 LTS.
`git-annex` was installed via conda using the command `conda install -c conda-forge git-annex`
```

Here is the complete error message:

### 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)
git-annex is an awesome tool! Really appreciate your work and everything else works great!
