Issue Description:

Was trying to compile the FirebaseSwift library on swift-4.2.1-RELEASE-ubuntu16.04 environment via the Perfect Assistant when I got this crash:

1. While emitting IR SIL function "@$S4Just10HTTPMethodO13FirebaseSwiftE11justRequestyAA10HTTPResultCAA24URLComponentsConvertible_p_SDySSypGAIypSgSDyS2SGSDySSAA8HTTPFileOGSS_SStSgAKSbSdSgSSSg10Foundation4DataVSgyAA12HTTPProgressVcSgyAGcSgtcvg".1. While emitting IR SIL function "@$S4Just10HTTPMethodO13FirebaseSwiftE11justRequestyAA10HTTPResultCAA24URLComponentsConvertible_p_SDySSypGAIypSgSDyS2SGSDySSAA8HTTPFileOGSS_SStSgAKSbSdSgSSSg10Foundation4DataVSgyAA12HTTPProgressVcSgyAGcSgtcvg". for getter for justRequest at /perfectbuild/.build/checkouts/FirebaseSwift.git-6480259082665391381/Sources/FirebaseSwift/HTTPMethod+justRequest.swift:15:9

Upon investigating the file, this seems like the most likely culprit

typealias JustSendRequestType =     (URLComponentsConvertible, [String: Any], [String: Any],     Any?, [String: String], [String: HTTPFile], (String, String)?,     [String: String], Bool, Double?, String?, Data?,     (TaskProgressHandler)?, ((HTTPResult) -> Void)?) -> HTTPResult

aside: this is my first bug report so I apologize in advance for poor formatting

We don't have access to view that GitHub repo. Can you make it public?

@belkadan Ah, sorry about that. Should be available now
