Issue in updating status due to the time interval when the job runs to fetch the events

[AayushChaudhary0001]

I found two issue while testing this plugin

Issue 01: Wrong text is shown for the status change.

Steps to reproduce:

1. Enable the MS calendar plugin
2. Open the ms calendar settings for Mattermost server via slash command
3. Then set 'Setting: Get Confirmation' to Yes
4. Also set 'Setting: Set Custom Status' to Yes
5. Now schedule a meeting from outlook calendar
6. Check the text shown for status change message.

Expected: Appropriate and accurate text should be shown.
Actual: Wrong text is shown for the status change.

Issue 02: Custom status is not getting updated properly

Steps to reproduce:

1. Enable the MS calendar plugin
2. Create two overlapping meeting from outlook calendar like - one from 10:00 am to 10:15 am and second from 10:15 am to 10:30 am
3. Check the custom status for second meeting

Expected: No delay should be there in updating the custom status of the second meeting
Actual: Around 4 min delay is found for the updation of custom status for the second meeting

Suggestion:- The reason behind both of the issues is the time interval for the job which runs to fetch the upcoming events planned in the next defined time interval.
