[FIX] web: CP keep the correct searchValue

Before this commit, in the command palette, during a search, it is possible
that the value entered is modified. The problem only occurs if the namespace
has a debounceDelay bigger than 0 and at least one of its command providers is async.

How to reproduce:
=================
- Go to the command palette with the @ namespace.
- Type a few characters
- Re-enter a few characters
If you repeat this operation several times, some characters may disappear.

Why:
====
The value of the input is modified at each "input" event, but the searchValue
in the state is only modified when the debounce trigger "search".
Since the command palette template is contained in a slot, each state
change causes a complete rendering of the command palette. When the search is executed,
the commands are added to the state after each provider has generated them,
so a rendering takes place and it is the value contained in state.searchValue
that is used for the input and not the value contained in it before the rendering.

Solution:
=========
No longer modify state.searchValue during the search, but at each input event.
