Error: EPERM: operation not permitted on Windows

[eliandoran]

Steps to reproduce:

1. Remove data directory.
2. Finish the first setup.
3. Restart the server.
4. Log in.

The error occurs only on Windows systems.

First discussed in #228 .

We get an error:

[Error: EPERM: operation not permitted, rename 'C:\Users\Elian\Projects\TriliumNext\data\sessions\WMCk1bAlG6HCBjNajFh-NPcVNZlF1dKn.json.1509196086' -> 'C:\Users\Elian\Projects\TriliumNext\data\sessions\WMCk1bAlG6HCBjNajFh-NPcVNZlF1dKn.json'] {
  errno: -4048,
  code: 'EPERM',
  syscall: 'rename',
  path: 'C:\\Users\\Elian\\Projects\\TriliumNext\\data\\sessions\\WMCk1bAlG6HCBjNajFh-NPcVNZlF1dKn.json.1509196086',
  dest: 'C:\\Users\\Elian\\Projects\\TriliumNext\\data\\sessions\\WMCk1bAlG6HCBjNajFh-NPcVNZlF1dKn.json'
}

followed by another:

The culprit appears to be session-file-store as per https://github.com/valery-barysok/session-file-store/issues/69. No straight-forward solution apart from replacing session-file-store with something else.

The issue is reproducible on Trilium Notes 0.63.7 as well, so not a regression.
