To find the common advertised speeds between $h1 and $h2, common_speeds_get() is called. Currently, the first speed returned from common_speeds_get() is removed claiming "h1 does not advertise this speed". The claim is wrong because the function is called after $h1 already advertised a subset of speeds. In case $h1 supports only two speeds, it will advertise a single speed which will be later removed because of previously mentioned bug. This results in the test needlessly failing. When more than two speeds are supported this is not an issue because the first advertised speed is the lowest one. Fix this by not removing any speed from the list of commonly advertised speeds.

[ Upstream commit 10fef9ca6a879e7bee090b8e51c9812d438d3fb1 ]

The test case check_highest_speed_is_chosen() configures $h1 to
advertise a subset of its supported speeds and checks that $h2 chooses
the highest speed from the subset.

To find the common advertised speeds between $h1 and $h2,
common_speeds_get() is called.

Currently, the first speed returned from common_speeds_get() is removed
claiming "h1 does not advertise this speed". The claim is wrong because
the function is called after $h1 already advertised a subset of speeds.

In case $h1 supports only two speeds, it will advertise a single speed
which will be later removed because of previously mentioned bug. This
results in the test needlessly failing. When more than two speeds are
supported this is not an issue because the first advertised speed
is the lowest one.

Fix this by not removing any speed from the list of commonly advertised
speeds.
