fix(tests): remove delays between dials

[danisharora099]

This is a bug report

Problem

nwaku<>js-waku interop saw flakiness when we dial two nwaku nodes, from js-waku, one after the other -- the connections seems to be dropping.

adding a small delay of 500ms between the two dials seems to have fixed it -- https://github.com/waku-org/js-waku/pull/1973/files

Proposed Solutions

1. Investigate why the delays needed to be add
2. Remove the delays

Maybe @fbarbu15 has any input or ideas on it.

Unfortunately no, I don't have any real clue what caused this flaky tests. Maybe a race condition?
