🐛 [RUM-2940] fix normalize URL for relative paths

[BenoitZugmeyer]

Motivation

Relative URLs are wrongly “normalized”, and those incorrect URL are used:

• to define the @resource.url in Resource events, giving a wrong information to customers
• to match the corresponding PerformanceTiming, so the SDK fails to find the corresponding timing, so the Resource event lacks detailed timings and size

Changes

Fix normalizeUrl and remove some unused functions

Testing

• Local
• Staging
• Unit
• End to end

I have gone over the contributing documentation.
