Fix forked repo has no icon and language stat.

[L0veSunshine]

Fix #10790
I'm not sure if sleep 1.5 seconds is a good method, but this method is simple enough, If the language stat indexer can't analysis code and write the result to database in 1.5 second, After you fresh the page the language stat will display.

[L0veSunshine]

Another solution is copy the older repo's language statistic from data base. But is a little bit troublesome. and re-index can be more accurate.

There is an unsolved issue: the original repo and the forked repo has different size on the information bar. It has no influence, but is very strange.

It would be better and faster just to copy stats from original repo

Thanks your suggestion, I will try another way.
Because i am not familiar with the repo and language stat structure, i use the most easy method.😂
May you give me some tip why the new repo and the original one's size is a little bit different. I worry that directly copy the language stat will cause errors by these difference.

[lafriks]

Size could probably be different because git mirror will not copy all refs but that just wild guess

One more question, thank you very much.
I am sorry i am not familiar with xorm framework,the operation in xorm is asynchronous or synchronous?
if the operations in xorm is asynchronous, how can i confirm the copy operation has done. only if the operation had finished then redirect url the language stat will be right.

[lafriks]

xorm operations are synchronous

[L0veSunshine]

xorm operations are synchronous

Thanks, i will have a try.
