Fixed #1674: duplicated route prefix in profiler urls

[adamwojs]

Steps to reproduce

1. Define prefix for profiler routes in Symfony application e.g,

# web_profiler.yaml 
# ...

web_profiler_profiler:
    resource: '@WebProfilerBundle/Resources/config/routing/profiler.xml'
    prefix: /prefix/_profiler

2. Configure plugin as described in phpstorm profiler #1674
3. Open profiler menu

Proposed patch

Proposed patch ignores everything before /_profiler/ segment (as is already part of the base url) when extracting profile URL from href attribute.
