Just reread all 3 articles. The first and third don't have a timeline, but posit that it will occur after the Model 3 has begun sales, so 2019. Seeking Alpha says Tesla is on track for bankruptcy, and posits that it might be by the end of the year (i.e., 12 months from the date of the article) but is otherwise anticipated for 2019 based on the numerous cash flow models in the article (assuming no stock offering or new debt issuance).

In other words: 3 months ago no one was saying Tesla would be bankrupt by August/September.

And here's the thing: if Musk was truly honest about Tesla not seeking financing or offering new stock in 2018, they are on track for bankruptcy by the end of the year based on currently available investor documents re expense, cash flow, assets, etc.. If those documents are wrong, it's incumbent on Tesla to update them, not on the rest of us to assume voodoo financial magic will save the day.
