### Description

This probably more than a year problem for me, before, i using this autocomplete for html src, and now it doesn't work at all

### Steps to Reproduce

1. Install Atom
2. Install Autocomplete Paths
3. typing //img src="./ or / or just explicit folder name doesn't work here"//

**Expected behavior:** [folder or file will show up on autocomplete]

**Actual behavior:** [folder or file not showing up]

**Reproduces how often:** [It's been a year!]

### Versions

The newest version of atom and autocomplete-paths

Start by reproducing the reported behavior in Atom with the autocomplete-paths package, using an HTML src attribute and the listed relative or explicit paths. Compare the expected folder or file suggestions with the actual absence of suggestions across the reported cases. Done means path autocomplete works for HTML src values in the reproduced scenarios.
