[USH-1238] "There are no posts yet" - Separate the text for when there are no posts & when no filters match

[Ifycode]

Solution implemented explained

• Show "There are no posts yet" text on feed view, when default filters is on (i.e. all 6 filter types are in default state) but there are no posts. There are 2 scenarios for this:
  • There are no posts at all in the deployment: You can test this by logging in as an admin for a deployment that has no posts at all.
  • There are posts in the deployment, but none can be viewed by a user due to the permissions they have.
• Show "No posts match the current filters. Please Change or Clear filters to see matching posts" text on feed view, when not default filters (i.e. at least one of the 6 filter types are in default state) and there's no matching post for user's filter selection/combination
• Search by keyword detection and no posts message:
  • Keyword search only (i.e. searching posts by keyword when Default filters is on): Use "No posts match your keyword search. Please change or clear keyword search to see matching posts".
  • Keyword search + filters applied (i.e. searching posts by keyword when not in default filters): Use "No posts match your keyword search + filters. Please change or clear keyword search and/or filters to see matching posts".

This works good, just a question, what does this change do?

Pasting answer here too for anyone interested:

What the change does - this.clearPostsResults(); is supposed to restore this.searchQuery to an empty string on page reload, so that the localStorage.setItem('USH_searchPostByKeyword', this.searchQuery); can be correctly set at that point. Otherwise, localstorage still has a previous value even though the search by keyword input field is cleared/empty on reload. No posts message will therefore not display the correct message we intend.
