Autocomplete ignores leading pipe symbol (`|`) for namespaced symbols

[eduardolevygp]

Describe the bug When a symbol from a different namespace starts with a pipe symbol, the autocomplete ignores it when you type it, causing duplication when you select the autocomplete item.

To Reproduce Steps to reproduce the behavior:

1. Create a namespace called foo, with a symbol called |bar in it.
2. In another namespace, require foo and type foo/, then trigger autocomplete
3. Type |ba and select |bar option on the autocomplete list
4. It'll result in foo/||bar

Expected behavior Consider the pipe symbol for the search when typed, removing it when it's replaced with the auto-completed value, avoiding duplication.

Desktop (please complete the following information):
