Can not set log level for "main" from wire-cell CLI.

Actually, I don't reproduce the problem:

$ cat minimal.jsonnet
local wc = import "wirecell.jsonnet";
local app = {
    type: "Pgrapher",
    data: {
        edges: []
    },
};
local cmdline = {
    type: "wire-cell",
    data: {
        plugins: ["WireCellPgraph"],
        apps: ["Pgrapher"]
    }
};
[cmdline, app]

$ wire-cell -l stderr -c minimal.jsonnet
[15:42:50.082] I [ timer  ] Timer: Total node execution : 0 sec

$ wire-cell -l stderr -L main:debug -c minimal.jsonnet
[15:41:30.301] D [  main  ] configuring component: "Pgrapher":""
[15:41:30.301] D [  main  ] executing 1 apps, thread limit 0:
[15:41:30.301] D [  main  ] executing 1 apps, thread limit 0:
[15:41:30.301] D [  main  ] executing app: "Pgrapher"
[15:41:30.301] I [ timer  ] Timer: Total node execution : 0 sec

It does look like the pgrapher timer needs to be changed to debug. But, I'm able to get "debug" messages from "main" printed.

@HaiwangYu please take a look at see if this fairly reproduces the problems you found.
