Use lazy classloading of stub index extensions with iterator in background thread instead of eager point.getExtensionList() during initComponent

find extension by class - efficient implementation, if no listeners, simply use iterator (so, only extensions from 0 to index of wanted are created) do not register interface extensions in pico container

terminal bash: remove unneeded export, unset __INTELLIJ_COMMAND_HISTFILE__ to not garbage environment

Use lazy classloading of stub index extensions with iterator in background thread instead of eager point.getExtensionList() during initComponent

The problem is that additional listener (that was removed with this commit)
overrides existing esc listeners of content.

Additional listener for esc is redundant because it's never get called.
`com.intellij.ui.popup.AbstractPopup#dispatchKeyEvent` prevents listeners
execution if it returns true. So, if `myCancelKeyEnabled` is `false`,
listener is not executed because of `if` condition and in case of `true`
listeners are not executed.

As long as this additional listener doesn't override existing listeners,
`hide()` function is called with `myEscListener`.
