Only last volume of manga is uploaded if parent folder contains a '.' character

[spacehamster]

There is an issue with this line nere

mokuro-reader/src/lib/upload/index.ts

Line 56 in a9f7bca

path = webkitRelativePath.split('.')[0]

If a file named "parent.directory/volume 01.mokuro" is uploaded, it will return "parent" as the volume path instead of the expected result of "parent.directory/volume 01". This results in subsequent volumes overwriting previous volumes.
