ImportAll should check for custom pull handler

[cambot]

Our project has a custom pull event handler that extends SourceControl.Git.PullEventHandler.IncrementalLoad and has no other compile dependencies. (After ##super() has run it does some additional work based on what was loaded)

I recently had to rebuild my local development instance. Once I was through the setup phase, I ran a forced import to load the code base and received this error:

==import start==
embedded-git-config.GSC has been imported from {{install dir}}\USER\embedded-git-config.json
==import done==
ERROR #5002: ObjectScript error: <CLASS DOES NOT EXIST>ForModifications+8^SourceControl.Git.PullEventHandler.1 *USER.Deployment.GitPullHandler

This is ForModifications+8:

set event = $classmethod(
    $select(
        $data(pullEventClass)#2: pullEventClass,
        1: ##class(SourceControl.Git.Utils).PullEventClass())
    ,"%New")

ImportRoutines() only loads all the artifacts without compiling anything. Compilation is deferred until OnPull() is run on the event handler class... which for fresh installs, is not compiled yet at this point.

I was able to modify ImportRoutines() to import and compile the pull handler class in my local with this (once the config json is loaded):

Set tPullEventClass = ##class(SourceControl.Git.Utils).PullEventClass()_".cls"
If $Data(itemList(tPullEventClass)) {
    Write !,"Importing pull handler: ",tPullEventClass
    Set ec = $$$ADDSC(ec, ..ImportItem(tPullEventClass, force, 1, 1))
}

This worked for me because I only have a single class to contend with. I suspect the better solution is fixing ForModifications() because any compilation dependencies should have been loaded by this point and only need to be compiled:

Set tPullEventClass = $Select(
        $Data(pullEventClass)#2: pullEventClass,
        1: ##class(SourceControl.Git.Utils).PullEventClass())
#; if the pull event class is in the list of modified files (meaning not provided by Embedded Git),
#;  then compile it and its dependencies with adequate error checks
Set event = $ClassMethod(tPullEventClass, "%New")
