player_transfer_history() throwing error for some players

[JaseZiv]

There was an issue similar to this (#127).

For some players, player_transfer_history() throws errors. It appears as though when the player retires, or either joins from 'Without Club' or ends up 'Without Club' is handled somewhat differently.

df <- player_transfer_history("https://transfermarkt.com/jack-rodwell/profil/spieler/57079")

Error in data.frame(player_name = as.character(player_name), season = as.character(season),  : 
  arguments imply differing number of rows: 1, 0

This is because of the fact that this player joined his current club from 'Without Club':

Following your fix of this error, there is now a problem with the country_from and country_to columns being empty or in some cases containing "Without club". The picture below is obtained by running the following code:

test <- player_transfer_history(player_urls = "https://www.transfermarkt.com/jack-rodwell/profil/spieler/57079")

The country_from and country_to values are no longer exposed for scraping as they once were. I haven't yet found an elegant solution to fix this so will reopen this issue
