Stack traceback with :Telescope frecency

[jyuan0]

After the recent OO refactor, running :Telescope frecency gives me the following error:

Error executing Lua callback: ...im/lazy/telescope-frecency.nvim/lua/frecency/recency.lua:30: bad argument #1 to 'ipairs' (table expected, got nil)

This is with a nightly Neovim build (v0.10.0-dev-766+gef44e5972). Please feel free to close this if it's just a bug on nightly, and if you need more info, please let me know. Thanks!

It seems your DB has file entries that have no related timestamps. I did a fix for those cases in #120.
