Which problem is this PR solving?

• part of: Upgrade react-router-dom to latest version #1825
• Upgrades react-router-dom to v5.2.0

Description of the changes

• This PR upgrades the rrd to v5.2.0
• This upgrade was previously attempted with PR feat: upgrade to react-router-dom v5.2.0 #727 but at that time, an issue (Searching spans in a trace page doesn't work #803) was reported because react-router-redux v5.x was not compatible with rrd v5.2.0, so it was reverted with PR: Downgrade react-router-dom (#803) #837
• Now, since we have redux-first-history instead of react-router-redux, we can upgrade to rrd v5.2.0 safely now.

How was this change tested?

• The reported issue with v5.2.0 (Searching spans in a trace page doesn't work #803) is not being reproduced now.
