Fix stop medication bug

[mgramigna]

Pull requests into Flux require the following. Submitter and reviewer should ✅ when done. For items that are not-applicable, note it's not-applicable (N/A) and ✅.

For Jira 1539 and the first bullet point of #506. We were trying to get the text typed before the "@" when selecting an active medication and the call we were making always returned empty string. Changing it to use the .text property of the anchor block fixes the bug.

To replicate the bug on master:

• Open a new note
• Type "#stop medication"
• Type "@"
• Do not type any other text and hit enter
• Select a medication. The medication name will disappear and there will be a console error
