fix test "search waypoint by GC code"

Ruchy: search waypoint by GC code                                     | FAIL |
Page should have contained element 'xpath=//*[@id="wynikWpt"]/img[@src="https://cdn.geokrety.org/images/icons/ok.png"]' but did not.

check this test:

• flaky wait ?
• need to review component locator value ?

[boly38]

• wynikWpt already present before search..
• result is updated on each keypress!
• sometime the last keypress event is not triggered with robots

---

• try simulate onblur after input like in this example

[boly38]

seems blur doesn't fix that issue !

maybe need to check javascript side on target env.

always produced :(

Element 'id=szukaj_img_ok' did not appear in 30 seconds.

TODO/ try just after redeployment, maybe there is some transient database unavailability at startup?
