Graphs for directories don't work in Windows due to path representation

[devdanzin]

Running wily graph src/wily/ raw.loc in Windows results in an empty graph. It turns out that it's due to failing to match paths with different path separators. Specifically, the line below fails to find a value that is present in the revision:

wily/src/wily/commands/graph.py

Line 85 in 72c4bb8

val = rev.get(config, state.default_archiver, operator, str(path), key)

To Reproduce

1. checkout wily's repo in Windows
2. wily build
3. wily graph src/wily/ raw.loc
4. See empty graph open in browser.

Expected behavior
A graph with many lines (for each tracked file in that directory) should open in the browser.

Desktop

• OS: Windows
• Version: 1.24.2

Fix
If we convert path to pathlib.Path(path) right after the following line, the graph is generated correctly:

wily/src/wily/commands/graph.py

Line 77 in 72c4bb8

for path in paths:

Once I test that this fix doesn't create issues in Linux, I'll submit a PR.
