[Bug 1651210] [NEW] If the name in manifest has uppercase letters the package is not installed correctly

[ET]

Public bug reported:

When you have upper-case letters in the name of the application the manifest file after install has wrong name, without upper-case. This creates an invalid installation. And the problem is not reported until you actually want to use the package.
Take this manifest.json as example:

phablet at ubuntu-phablet:~/tmp/ResistorCalculator$ cat manifest.json
{
    "architecture": "all",
    "description": "Electrict resistor color code calculator",
    "framework": "ubuntu-sdk-15.04",
    "hooks": {
        "resistor-calculator": {
            "apparmor": "Resistor.apparmor",
            "desktop": "Resistor.desktop"
        }
    },
    "maintainer": "me<me at yahoo.com>",
    "name": "com.edi.ResistorCalculator",
    "title": "Resistor Calculator",
    "version": "0.9"
}
