Fix highlighting the condition in accordion after creating it

[hstastna]

Fixes:
https://bugzilla.redhat.com/show_bug.cgi?id=1683697

What:
Fix highlighting condition in accordion right after creating it: the newly created condition was not highlighted in accordion as expected, instead of that, All Conditions node was highlighted. Everything else regarding adding new conditions seems to work.

Steps to reproduce:

1. Navigate to Control > Explorer, then Conditions > Replicator Conditions ,or any other conditions
2. Create a new condition: choose Configuration > Add a New Container Replicator Condition or any other type of condition (depends on step 1)
3. Fill in required fields (description and expression), values are not important
4. Click on Add button
   => All Conditions node highlighted instead of newly created condition

TODO: (done)

• specs
• test all other types/classes of conditions if it works
• check this also in :policy_tree, :policy_profile_tree - there is similar code for setting a new node

Details:
@new_condition_node was set incorrectly (see https://github.com/ManageIQ/manageiq-ui-classic/pull/5302/files#diff-4b771fc8b6101d357855d3d10d79ba8aL69), while adding a new condition, it was set for example to
"xx-containerreplicator..." instead of
"xx-containerReplicator..."

@skateman What do you think about the specs? :-)

Checked commits hstastna/manageiq-ui-classic@e8f4580~...34ee4f1 with ruby 2.3.3, rubocop 0.52.1, haml-lint 0.20.0, and yamllint 1.10.0

Everything looks fine. 🍪

I think they're good enough, but this has to be tested in the UI as well.
