Adapt copy conflict changes

[MarcelGeo]

When file is updated and created on the server and user is having the same file (with same checksum) - do not create conflicting copy. This change will be ignored during pull:

• no download of a file from server
• no changes are adapted to users local directory
• no copy conflict if checksum of a file is the same as in users directory

Simulation NO conflicts -> CREATE - CREATE ✅

• create project
• download project to 2 clients
• create project version from client 1 - local.txt with some content ("Hello!") -> PUSH
• create the same file in client 2 local directory
• sync changes into client 2
• file will be there and no conflicitng copy for local.txt file created

Simulation CONFLICTS -> CREATE - CREATE ✅

• create project
• download project to 2 clients
• create project version from client 1 - local.txt with some content ("Hello!") -> PUSH
• create the same file in client 2 local directory but with different content ("Hello world!)
• sync changes into client 2
• file will be there from server with content Hello! and conflicitng copy for local.txt file created with Hello world!

Simulation NO conflicts -> UPDATE - UPDATE ✅

• create project
• download project to 2 clients
• create project version from client 1 - local.txt with some content ("Hello!") -> PUSH
• sync changes to client 2 - local.txt file is created
• update file local.txt in client 1 directory ("Hello world!") -> PUSH
• update file local.txt from client 2 directory ("Hello world!")
• sync changes into client 2
• file will be there with content Hello world! and no conflicitng copy for local.txt file created

Simulation CONFLICTS -> UPDATE - UPDATE ✅
Note: no changes in file preview on web - new bug #3308

• create project
• download project to 2 clients
• create project version from client 1 - local.txt with some content ("Hello!") -> PUSH
• sync changes to client 2 - local.txt file is created
• update file local.txt in client 1 directory ("Hello world!") -> PUSH
