[BUG] Difficulty finding problems with both id and alias set to single character.

[Aritra8438]

Let's say, we have a problem with name and alias both set to 'a'.

If we want to add the same problem to a contest, we need to find it in the search box which only emits update-search-result-problems if searchType has at least (activation-threshold) 2 letters.

<omegaup-common-typeahead
  class="w-75"
  :existing-options="searchResultProblems"
  :activation-threshold="2"
  :value.sync="alias"
  @update-existing-options="
                  (query) =>
                    $emit('update-search-result-problems', {
                      query,
                      searchType: selectedSearchType,
                    })
                "
></omegaup-common-typeahead>

So, we can't add the problem to the contest.

Expected Behavior

• The users and developers expect the problem to be found on search.

to reproduce this bug:

1. Create a problem with both alias and name set to a.
2. Try to add the problem to a contest.
3. You can't find the problem as search triggers if there are at least two characters.

As @pabo99 mentioned, the two possible solutions are:

• Add validation to all forms so that at least 2 characters are required. In this case, it will be necessary to run a query in production to see if there is currently any item that meets this criterion (else we can't find that problem on searching).
• Set the activate-threshold to 1.

I want to solve it accordingly.
