git add without -- branch does not add initialBranch master

[steveriggins]

or conversely, if initialBranch is missing, then git add of a module that does not have initialBranch in the dependencies tries to add --branch (null)

{
"dependencies" : [
{
"name" : "CocoaLumberjack",
"moduleURL" : "git@github.com:CocoaLumberjack/CocoaLumberjack.git"
}
],
"dependenciesPath" : "../",
"initialBranch" : "master",
"sourcePath" : "Shrubbery/THGLog.xcodeproj",
"name" : "Shrubbery"
}

will fail if someone tries to add this module to their project. However:

{
"dependencies" : [
{
"name" : "CocoaLumberjack",
"moduleURL" : "git@github.com:CocoaLumberjack/CocoaLumberjack.git"
"initialBranch" : "master",
}
],
"dependenciesPath" : "../",
"initialBranch" : "master",
"sourcePath" : "Shrubbery/THGLog.xcodeproj",
"name" : "Shrubbery"
}

works
